Abstract: An intra-vaginal or intra-anal sheath for use as a contraceptive and as a prophylactic for protection against sexually transmitted diseases such as AIDS. The sheath includes a portion (1) defined by a tubular membrane made of flexible material (2) and shaped to receive the male sex organ, and a portion (3) defined by a thin film (4) and designed to be held within the vagina, said portion (3) being provided with an internal scissor-like retaining assembly (6). An applicator for said sheath includes two cylindrical members (14, 15) joined together such that they can be in an inoperative released position when the 'male' cylindrical member (15) is inserted into the 'female' cylindrical member (14), and in an extended position when the two members are mutually locked and the second cylindrical member (15) is partially located outside the first cylindrical member (14) to enable insertion of the sheath.

Title: Procede de transmission par canal indicateur de tele-appel dans un systeme de communication mobile amrc
Inventor: ZHU JINGNING
IPC: H04W68/00
Filed: 2002-02-20
Abstract: L'invention concerne un procédé de transmission par canal indicateur de télé-appel dans un système de communication mobile AMRC. Le procédé consiste à transmettre un signal uniquement lorsqu'un matériel d'abonné comprend un message de télé-appel dans un bit indicateur. Lorsque le matériel de l'abonné n'a pas de message de télé-appel et que le bit indicateur est placé sur zéro, le signal transmis est coupé. Dans le cas où le canal indicateur de télé-appel prend en charge les abonnés de télé-appel Np de 144 et le nombre total de bits est de 288, si seulement un abonné est appelé, alors il suffit de transmettre uniquement deux bits, et le reste des 286 bits ne doit pas être transmis afin d'économiser l'énergie. Par conséquent, comparé au procédé de la transmission par canal indicateur de télé-appel existant, le procédé de la présente invention est capable de réduire la puissance d'émission, de diminuer les parasites et d'augmenter la capacité du système dans son ensemble.

IPC: F16K1/52
Filed: 2002-11-26
Abstract: La présente invention concerne une vanne d'arrêt inverse présentant des propriétés supérieures d'arrêt, d'obturation, de réglage ou de réduction. Par rapport aux modèles existants de vanne d'arrêt, on a ajouté dans le bas du corps (4) un segment de conduit droit ouvert dans le bas, le clapet (7) venant sous le siège (5). Ainsi, le fluide pénètre dans le corps de banne de pas le dessous du siège. La partie inférieure du siège peut comporter un épaulement. Un cordon circulaire peut garnir le pourtour du clapet pour le protéger. La tige (9) se termine par un corps tronconique de régulation de la pression et du débit. Cette vanne admet six types de mécanismes de coulissement vertical empêchant la rotation de la tige. On arrive ainsi à limiter l'usure des pièces concernées et à prolonger la durée de vie, et ce, tout en satisfaisant aux normes de pression de la main, de pose du pied, d'ouverture rapide hydraulique et de fermeture rapide. Avec cette construction, la vanne de l'invention présente l'avantage d'être bon marché, de ne pas fuir, d'économiser l'eau et la matière, de ne pas consommer d'électricité, de se fermer et de s'ouvrir rapidement, de s'installer et de s'entretenir facilement, de correspondre à de nombreux cas d'emploi, tout en étant économiquement et socialement attractive.

Title: Injection moulding screw seal - comprising ring which rotates with screw to reduce wear
IPC: B29C45/52
Filed: 1971-02-12
Abstract: A method for effecting the injection operation in injection moulding and blowing machines, with a revolving and axially removable screw, and using a non-return device formed by a damming ring, has this damming ring so constructed that it is compelled to rotate at the same speed as the screw. In the prefd. appts., the dam ring is axially slidable upon a portion of the screw shaft between the conical head and the front end of the bladed portion of the screw. The inside aperture of the ring has shoulders which bear against corresponding shoulders on the shaft of the screw, thus causing the ring to rotate with the screw. The rotation avoids friction between ring and screw thus considerably reducing wear.

Title: In situ. testing of shock absorbers - involves pneumatic piston gives step input to damped oscillatory suspension system
Inventor: MORITZ JOSEF ING
IPC: G01M17/04
Filed: 1971-06-28
Abstract: The vehicle wheel, normally mounted in its axle with shock absorber and springing, is supported on teh piston of a pneumatic ram. On the collar around the piston of the ram is a latch arrangement which holds the ram in a lower position. When this latch, is released the air pressure in the system results in the rapid rise of the piston to a higher position. The air pressure in the cylinder is monitored. This step input to the damped cantilever arm of the suspension results in overshoot which has to conform to a specification limit. A follower in contact with the wheel rim records the displacement and oscillation of the system.
